The origin of many of the defining features of animal body plans, such as symmetry, nervous system, and the mesoderm, remains shrouded in mystery because of major uncertainty regarding the emergence order of the early branching taxa: the sponge groups, ctenophores, placozoans, cnidarians, and bilaterians. The "phylogenomic" approach [1] has recently provided a robust picture for intrabilaterian relationships [2, 3] but not yet for more early branching metazoan clades. We have assembled a… Expand
Placozoans are eumetazoans related to Cnidaria
TLDR
It is necessary to reconsider the homology of eumetazoan traits not only between ctenophores and bilaterians, but also between cnidarians and bizards, as well as between placozoans and poriferans. Expand
A Large and Consistent Phylogenomic Dataset Supports Sponges as the Sister Group to All Other Animals
TLDR
The reconstruction of deep metazoan relationships using a 1,719-gene dataset with dense taxonomic sampling of non-bilaterian animals that was assembled using a semi-automated procedure, designed to reduce known error sources outperforms previous metazoa gene superalignments in terms of data quality and quantity. Expand
Employing Phylogenomics to Resolve the Relationships among Cnidarians, Ctenophores, Sponges, Placozoans, and Bilaterians.
TLDR
Past phylogenomic studies and potential causes of systematic error are reviewed in an effort to identify areas that can be improved in future studies and caution against dismissing novel hypotheses merely because they conflict with historical viewpoints of animal evolution. Expand
Phylogenomic Analyses Support Traditional Relationships within Cnidaria
Cnidaria, the sister group to Bilateria, is a highly diverse group of animals in terms of morphology, lifecycles, ecology, and development. How this diversity originated and evolved is not wellExpand
Phylogenomic Analyses Support Traditional Relationships within Cnidaria

A Look Back Over 20 Years of Evo-Devo Studies on Sponges: A Challenged View of Urmetazoa
TLDR
This chapter focuses on the evo-devo approaches applied to Porifera and how the data have changed the authors' view of these uncommon animals and how it challenges previous concepts of the last common metazoan ancestor. Expand
The phylogenetic position of ctenophores and the origin(s) of nervous systems
TLDR
It is argued that characters like neuropeptide signaling, ciliary photoreceptors, gap junctions and presynaptic molecules are consistent with a shared ancestry of nervous systems, however, that phylogenetic-tree construction artifacts may have placed ctenophores too deep in the metazoan tree. Expand
Putting Animals in their Place within a Context of Eukaryotic Innovations
TLDR
The current understanding of animal evolutionary relationships is reviewed, including which of the basal metazoan phyla (Porifera, Placozoa, Cnidaria, or Ctenophora) is basal-most, the branching order of the three major lineages of Arthropoda, the relationships within Lophotrochozoa, and the placement of several so-called minor groups such as Chaetognatha. Expand
Extracting phylogenetic signal and accounting for bias in whole-genome data sets supports the Ctenophora as sister to remaining Metazoa
TLDR
The phylogeny supports the still-controversial position of ctenophores as sister group to all other metazoans and provides a workflow and computational tools for minimizing systematic bias in genome-based phylogenetic analyses. Expand
Insights into bilaterian evolution from three spiralian
Current genomic perspectives on animal diversity neglect two prominent phyla, the molluscs and annelids, that together account for nearly one-third of known marine species and are important bothExpand

Broad phylogenomic sampling improves resolution of the animal tree of life
TLDR
This data reinforce several previously identified clades that split deeply in the animal tree, unambiguously resolve multiple long-standing issues for which there was strong conflicting support in earlier studies with less data, and provide molecular support for the monophyly of molluscs, a group long recognized by morphologists. Expand
Poriferan paraphyly and its implications for Precambrian palaeobiology
TLDR
It is demonstrated, in accordance with previous molecular studies, that sponges are paraphyletic, and that calcisponge are more closely related to eumetazoans than they are to demosponges. Expand
Concatenated Analysis Sheds Light on Early Metazoan Evolution and Fuels a Modern “Urmetazoon” Hypothesis
TLDR
The sum of morphological evidence, the secondary structure of mitochondrial ribosomal genes, and molecular sequence data from mitochondrial and nuclear genes that amass over 9,400 phylogenetically informative characters from 24 to 73 taxa are analyzed to provide evidence that Placozoa are basal relative to all other diploblast phyla and spark a modernized “urmetazoon” hypothesis. Expand
Sponge paraphyly and the origin of Metazoa
TLDR
The polymerase chain reaction is used to amplify almost the entire nucleic acid sequence of the 18S rDNA from several hexactinellid, demosponge and calcareous sponge species to suggest that sponges are paraphyletic, the Calcarea being more related to monophyletic Eumetazoa than to the siliceous spongees.

Improvement of molecular phylogenetic inference and the phylogeny of Bilateria

TLDR
The sister-group relationship of Platyhelminthes and Annelida to the exclusion of Mollusca, contradicting the Neotrochozoa hypothesis, and, with a lower statistical support, the paraphyly of Deuterostomia are discussed in an evo–devo framework. Expand
Multigene analyses of bilaterian animals corroborate the monophyly of Ecdysozoa, Lophotrochozoa, and Protostomia.
TLDR
This study demonstrates that the incongruences observed between rRNA and multigene analyses were indeed due to long-branch attraction artifacts, illustrating the enormous impact of systematic biases on phylogenomic studies and suggests that urochordates are more closely related to vertebrates than are cephalochordates.

TLDR
The Hox-based patterning system operating along the antero-posterior axis of the Bilateria does not seem to predate their divergence with the Cnidaria, but intercellular signalling systems could have been involved in generating the main body axis in the last common ancestor of the Metazoa. Expand
Phylogeny and evolution of glass sponges (porifera, hexactinellida).
TLDR
This rDNA phylogeny agrees well with the traditional classification and a previously proposed phylogenetic system, which ascribes to a more informative morphology in Hexactinellida, and recovers Porifera as monophyletic, although support for this clade is low under paired-sites models. Expand
Toward Resolving the Eukaryotic Tree: The Phylogenetic Positions of Jakobids and Cercozoans
TLDR
The first large-scale eukaryotic phylogeny is reported, inferred from 143 nucleus-encoded proteins comprising 31,604 amino acid positions, that includes jakobids, malawimonads and cercozoans, and compelling support is obtained for the monophyly of JEH group, Euglenozoa plus Heterolobosea (JEH group), and for the association of cer cozoans with stramenopiles plus alveolates. Expand
Animal phylogeny and the ancestry of bilaterians: inferences from morphology and 18S rDNA gene sequences
TLDR
Because chaetognaths and lophophorates, taxa traditionally allied with deuterostomes, occupy basal positions within their respective protostomian clades, deuterstomy most likely represents a suite of characters plesiomorphic for bilaterians. Expand
